The quests in my pip-boy are all greyed out and marked as finished. I'm level 49 and have discovered most of the map. Finished all the DLC's too.

I only have the "Don't Tread on the Bear" quest highlighted but that leads to nowhere (no marker on pip-boy etc)/

I'm with the NCR. Have killed Dr House, and am idolized in Hoover Dam and in the rest of the NCR holds.

I've been wandering around... lost.

Then I read some of the wiki - about a General Lee Oliver who is supposed to give me a quest called "Eureka" so that I can end the game...

But this quest isn't marked anywhere. I'm currently scouring Hoover Dam searching for this General to speak to him.

I'm posting because I'm suspecting the game's gone broken on me?

[Edit: the last part of the MQ I did was saving President Kimball at Hoover Dam].
